Abstract (en)
[origin: DE102005018059A1] Method for linking a silane (IIa) for producing a product, which is a component (III) in double-fold, three-fold or in higher amounts, or for cross-linking a condensate, a partial condensate, polymers or partial polymers, containing structural units (IIb) over the bond R 1>, comprises reacting (IIa) or its isomer, a transesterification product or a condensation product, which results by loss of an alcohol molecule of the silane, or a condensate, a partial condensate, a polymer or a partial polymer, containing (IIb), with a carbonyl compound (IV). Method for linking a silane (IIa) of formula (B 1>-R 1>(Y 1>)-Ra) a(Rb) bSi(X 1>) 4-a-bfor producing a product, which is a component (III) of formula (B 1>-R 1>-Ra) a(Rb) bSi(X 1>) 4-a-bin double-fold, three-fold or in higher amounts, or for cross-linking a condensate, a partial condensate, polymers or partial polymers, containing structural units (IIb) of formula (B 3>-R 1>(Y 1>)-Ra) a(Rb) bSi(OR 4>) d(X 1>) 4-a-b-dover the bond R 1>, where (IIa) or its isomer, a transesterification product or a condensation product, which results by loss of an alcohol molecule of the silane, or a condensate, a partial condensate, a polymer or a partial polymer, containing (IIb), reacts with a carbonyl compound (IV) of formula (Q-R 5>(-Qa) c). Ra : open-chain and/or cyclic alkyl-, aryl- or alkylaryl with 1-10C atoms, interrupted by one or more of O or S atoms or carboxyl or amino groups or such atoms/groups prevents the silicium atom at their end; R 1>a group substituted with Y 1>, alkyl-, aryl- or alkylaryl with 1-10C atoms, interrupted by one or more of O or S atoms or carboxyl or amino groups or such atoms/groups at their end; Rb : open-chain and/or cyclic alkyl-, aryl- or alkylaryl, preferably 1-20C alkylaryl; B 1>organically polymerizable group with at least one C=C-double bond and at least 2 carbon atoms; X 1>a group, which is obtained under the formation of Si-O-Si-bridges in a hydrolytic condensation reaction; Y 1>-OH or -COOH; a : 1 or 2; b : 0 or 1; B 3>a polymerizable group as in B 1>or such a group, whose double bond is already reacted; R 4>a bond to another silicium atom, optionally partially also to another metal atom, which can be built into silicic acid hetero polycondensation products, and optionally partially also hydrogen; d : 1-3; Q, Qa : NCO, -OH or -C(O)Xa; C(O)Xa : a group of carboxylic acids or an activated carbonyl compounds; c : 1-6; and R 5>a single bond and the rest of any group with c+1 valency (where R 5>is present only in exceptional cases, when Q and Qa are activated carboxylic acid groups and c is 1 ). When Q and/or Qa is -NCO or -C(O)Xa, then Y 1>in (IIa) or (IIb) is OH; and when Q and/or Qa is -NCO or -OH, then Y 1>in (IIa) or (IIb) is COOH. Independent claims are included for: (1) a silane of formula (V); (2) a condensate or a partial condensate comprising structural units of formula (VI); and (3) a polymer or a partial polymer comprising structural units of formula (VII).
